  • Patent number: 10677369
    Abstract: Embodiments are directed to a temperature calibration system that includes a closed fluidic system, such as a thermosiphon or a heat pipe. The closed fluidic system includes a valve for fluidly separating components therein from each other. In one embodiment, the closed fluidic system is a thermosiphon (or a heat pipe) and the valve is configured, in a closed state, to cover a port of the condenser to fluidly separate the condenser from other components of the thermosiphon. The valve may be a passively activated valve or an electrically actuated valve. In some embodiments, the valve is thermally actuated such that the valve changes state in response to changes in temperature.

  • Patent number: 9028235
    Abstract: A method and apparatus for moving along a tube extrusion line. An extruded tube is pushed through the extrusion line, by means of pressure generated by an extruder, to a withdrawal unit that takes over further driving of the tube. In a first-moving along phase, in which the tube has not yet passed a sealing of a calibration cooling unit relative to the atmosphere, the latter is under atmospheric pressure. In a second phase, in which the tube has passed the sealing, the calibration and cooling unit is placed under underpressure. In the first phase, the tube is supported either by internal overpressure or by a mechanical inner guide. A support cylinder extends axially from a casing head of the extruder and extends coaxially into a calibration sleeve in a first section of the calibration and cooling unit. A support plate is disposed between the casing head and an inlet of the calibration sleeve and provides external support for a tube exiting the casing head.

To achieve the purpose, the surfaces of the chutes 21, 22 are roughened by sandblasting. The chutes 21, 22 are made of metal such as stainless steel, for example. Processed metal surfaces are generally smooth with almost no friction. Moreover, metal has its inherent water repellency. If water is flowed on a bare metal surface, some parts do not get wet while some parts have concentrated surge water flow thereon. However, by sandblasting the surfaces of the chutes 21, 22, adequate friction resistance is generated and inherent water repellency of metal is eliminated.

    Abstract: A method and system for melt processing a thermoplastic composition that contains a starch and plasticizer is provided. The composition is melt blended and extruded through a die to form an extrudate, which is thereafter cooled using a multi-stage system of the present invention that includes at least one water-cooling stage and at least one air-cooling stage. More particularly, the extrudate is initially contacted with water for a certain period time so that it becomes partially cooled and solidified on its surface. After the water-cooling stage(s), the extrudate is also subjected to at least one air-cooling stage in which a stream of air is placed into contact with the extrudate.

  • Patent number: 8317503
    Abstract: A device for producing Lyocell fibers which are extruded from a cellulose solution of water, cellulose and tertiary amine oxide in a spinning head (25). The cellulose solution is obtained in a number of process steps directly from the cellulose (3, 4) or with the formation of a cellulose suspension. Since the degree of polymerization decreases in the course of processing the cellulose through to its extrusion in the cellulose solution, with the processing of celluloses with a low degree of polymerization there is the risk that the endless molded bodies (2) extruded in the spinning head (25) exhibit defective quality.

    Abstract: The present invention generally relates to a cooling process and system that can be utilized in the manufacture of flexible elongate extruded materials, such as tubing or jacketed electrical wire and cable. More particularly, the present invention relates to a cooling trough for cooling flexible elongate extruded materials after extrusion. Cooling trough embodiments have a base, a wet cooling chamber above the base, and an air dry chamber above the wet cooling chamber. The base contains a reservoir for collecting and storing a cooling liquid. An extruded material, such as a cable, enters the wet cooling chamber, where the cooling liquid from the reservoir is sprayed onto the material, the material is then passed to the air dry chamber where it is dried.
